I've recently noticed that Milo sits weirdly. His thighs sort of angle inwards towards his torso so that his feet and at an outward angle. Then he eventually slides out like he's doing the splits (probably because he's on tiled floors). I've heard of the 'kelpie sit' but I've never seen it. Is this the 'kelpie sit' or some hip problems? I haven't got a picture of it unfortunately!
